New technology for the treatment of femoral head necrosis

summary

The severe necrosis of femoral head needs artificial joint replacement. In the later stage of necrosis of the femoral head, the collapse of the femoral head is usually caused. Once the collapse is more serious, artificial joint replacement should be selected. This kind of operation has its own indications, technical requirements and complications, so it should be carefully selected. To tell you the truth, I used to have avascular necrosis of the femoral head. Now let me talk to you about the new technology for the treatment of avascular necrosis of the femoral head.

New technology for the treatment of femoral head necrosis

First, osteotomy: the necrotic area was removed from the weight-bearing area of the femoral head, and the non necrotic area was removed from the weight-bearing area. Clinical osteotomy includes varus or valgus osteotomy, trans trochanteric osteotomy and so on.

Second: patients can be operated within 1-3 weeks after operation. The method of exercise is to contract and relax the muscles of the front group of the thigh, mainly the quadriceps femoris, when the knee joint is still. Put the lower limbs flat on the bed, straighten the knee joint, push down the heel to extend the back of the foot, each time lasting for 3-10 seconds, repeat 10-20 times, 2-3 times a day. At the same time, make the ankle joint extend back, do plantar flexion and toe extension and flexion activities.

Third: MRI can examine our femoral head necrosis, MRI can clearly see the response of our soft tissue and the histological changes of the lesion area, which is the most sensitive and accurate method for early femoral head necrosis.

matters needing attention

Let me sum up: we should try to drink less, which kinds of high alcohol we should drink less, and try not to drink.
